PC restarting itself

My PC restart it self up when i tried to shut down the system for the night, but instead it reboot itself and a message would pop up on my desktop that said "Your system just recovery from a serious error"

Here is my mini dump log and please suggest ways to solve this issue.

The dmp error messages are not easily read by many machines... Can you get it to post in a Text file?
But most of these errors are simple problems caused by inadequate memory, hard drive issues, cooling fans, cpu fans, optical drives, and especially video graphics cards or drivers.
Please tell us more about your computer brand and model, operating sytem, and configuration, or motherboard brand and model... along with the amount of memory installed.
